4x-4y=2
16x+8y=14
2%284x-4y%29+=2%2A+2
==> +8x+-8y+=4
16x+%2B8y=14
Add these vertically...
==> +24x++=+18+
==> +24x%2F24++=+18%2F24+
==> +x++=+0.75+
Now plug in the value, x = 0,75 in the first equation...

4%280.75%29-4y=2

==> +3+-+4y=2
==> +3+-+4y+-3=2+-3
==> -4y=+-1+
==> -4y%2F-4=+-1%2F-4+
==> +y=+0.25+
x = 0.75
y= 0.25
